Description

Technical Field

[0001] The invention relates to the technical field of crane boom transfer transportation, in particular to a foldable boom section set platform. Background Art

[0002] Crawler cranes generally include a large number of main booms, tower booms and auxiliary boom sections with different cross-sections. Transporting a 12m long boom section (or two 6m long boom sections) alone requires more transport vehicles, while transporting different cross-sections together can reduce the number of transport vehicles and reduce transportation costs.

[0003] The invention patent (patent name: An adjustable truss arm transport set device, publication number: CN107381381A, patent number: ZL201710779734.8) discloses a transport arm set device, such as Figure 1 and Figure 2 As shown in the figure, the boom section can be directly installed after being inserted, without adjusting the position of the inserted boom section and changing the lifting position, but there are still the following disadvantages:

[0004] 1. During the assembly process, when the tower arm (middle-section arm section) is inserted into the main arm (large-section arm section), the second roller in the assembly device needs to be taken out as a whole. When the auxiliary arm (small-section arm section) is introduced into the tower arm (middle-section arm section), the second roller in the assembly device needs to be installed back, which is time-consuming and laborious.

[0005] 2. During the assembly process, when the tower boom (middle-section boom section) is introduced into the main boom (large-section boom section), and when the jib (small-section boom section) is introduced into the tower boom (middle-section boom section), an auxiliary crane or other equipment is needed as an auxiliary power source to drag the wire rope end and pull the tower boom into the main boom. Similarly, pulling the jib into the tower boom is not labor-saving and uneconomical.

[0006] 3. Although the suit device can be retracted horizontally and vertically when not in use to reduce the space occupied, when it is used, the retracted parts of the suit device need to be unfolded one by one and adjusted to an adjustable state, which requires a long adjustment time and a long preparation time for the suit; in addition, after the suit device is retracted, it still occupies a large space. Summary of the invention

[0007] In view of the deficiencies of the prior art, the present invention provides a foldable boom section suit platform.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A foldable boom section set platform, comprising a main chord, a cross bar, and a first roller bracket, characterized in that it also comprises a first platform and a second platform connected end to end for supporting the boom section, wherein both the first platform and the second platform comprise two main chords longitudinally arranged above and below and at least two cross bars, the two ends of which are respectively connected to the two main chords above and below and arranged transversely, and the cross bar on the first platform is longer than the cross bar on the second platform; at least two first pads are arranged on the two main chords of the first platform, and the first pads are used to support the first cross-section boom section; at least two roller brackets are arranged on the two main chords of the second platform, and the roller brackets comprise a first roller bracket and a second roller bracket laterally extended from the first roller bracket, and the first roller bracket is used to support the second cross-section boom section, and comprises a first bracket body arranged on the main chord and a first roller mounted on the first bracket body, and the second cross-section boom section is placed on the first roller; the second roller bracket is used to support the third cross-section boom section, and comprises a second bracket body arranged on the cross bar, a second roller bracket body movably connected to the second bracket body, and a second roller mounted on the second roller bracket body, and the third cross-section boom section is placed on the second roller.

[0010] The first cross-section boom section is a large cross-section boom section, the second cross-section boom section is a medium cross-section boom section, and the third cross-section boom section is a small cross-section boom section, which are respectively equivalent to the main boom, tower boom, and auxiliary boom in the prior art.

[0011] Furthermore, at least two pairs of first pads are symmetrically arranged on the two main chords of the first platform, and at least two pairs of roller brackets are symmetrically arranged on the two main chords of the second platform, and the heights of each pair of first pads and each pair of roller brackets increase successively from the head end of the first platform to the tail end of the second platform, forming a gradient distribution.

[0012] The height of the roller bracket is arranged according to a preset inclination angle, that is, the first roller and the second roller are arranged according to a preset inclination angle, so that the component force of gravity along the arm sleeve direction can be used to offset most of the resistance in the arm sleeve process, so as to achieve the purpose of labor saving.

[0013] The movable connection between the second bracket body and the second roller bracket body can realize two assembly forms of the second roller bracket in the working state and the non-working state. For example, the second bracket body and the second roller bracket body are connected together by a pin shaft, and the conversion of the two states is realized by rotating the pin shaft, as follows:

[0014] When the arm section needs two layers of sets, the second roller bracket is switched to a non-working state, that is, the pin is rotated, and the second roller rotates downward with the second roller bracket body until the second roller is in the lowest position, and then the first-section arm section is placed on the first platform, and the second-section arm section is placed on the second platform; at this time, because the second-section arm section has a preset inclination angle with the ground, multiple people can push the second-section arm section along the arm-set direction to guide it into the first-section arm section, and pass through the arm section roller of the first-section arm section until it is completely inserted.

[0015] When the arm section needs to be installed in three layers, the second-section arm section is installed first, and the second roller bracket is switched to the working state, that is, the pin is rotated, and the second roller rotates upward with the second roller bracket body until the second roller is in the highest position, and then the third-section arm section is placed on the second platform; at this time, because the third-section arm section has a preset inclination angle with the ground, multiple people can push the third-section arm section along the arm installation direction to guide it into the second-section arm section, and pass through the arm section rollers of the second-section arm section until it is completely installed. When transporting, the installed arm section can be lifted as a whole and placed in the transport vehicle, and the disassembly process is the opposite.

[0016] Furthermore, both the first platform and the second platform are truss-type brackets, and the truss-type bracket is provided with at least one web in the unit space surrounded by the main chord and the cross bar. The web is generally arranged at an angle, and the two ends are respectively arranged on the main chord and the cross bar. However, when it is necessary to evenly distribute the roller brackets, a section of the web can be extended laterally inward from the main chord, so that the second bracket body can be arranged on such a laterally extended web.

[0017] Furthermore, the first platform is configured as at least one truss-type support section, and the second platform is configured as at least one truss-type support section, and the two truss-type supports are rotatably connected, so that the suit can be folded at least once, which greatly reduces the occupied area of ​​the suit and takes very little time to unfold and collapse.

[0018] Furthermore, at least two support frames are provided on the two main chords of the second platform. The support frames are used to place the main chords of the first platform. The support frames are blocks with concave upper portions that match the shape of the main chords of the first platform.

[0019] Furthermore, the support frame is provided with a second gasket whose shape fits the support frame; preferably, the second gasket is fixed to the support frame by bolts, and the second gasket is made of flexible material to ensure flexible contact between the first platform and the second platform; the support frame is used to support the first platform, and after the multiple arm sections are assembled, the assembled platform of the present invention is folded, the first platform is rotated around the pin shaft, and placed in the support frame on the second platform, and the unfolding process is the opposite, which is quick and convenient.

[0020] Furthermore, the first cushion block and roller bracket are separate parts that can be assembled by pin connection or thread connection; this facilitates the maintenance of the cushion block and roller bracket. When they are broken, they can be removed for maintenance without the need to transport the entire set platform to a fixed point for maintenance.

[0021] Furthermore, a first gasket is fixedly disposed on the first cushion block.

[0022] Preferably, at least two first pads are symmetrically arranged on the two main chords of the first platform.

[0023] Preferably, the first gasket is fixed to the first gasket block by screws. The first gasket is made of a flexible material in order to ensure flexible contact between the first platform and the arm section to prevent damage to the arm section.

[0024] Furthermore, the main chord, cross bar and web are all welded or assembled from any one of seamless steel pipes, rectangular pipes, angle steels and plates; the connection points between the main chord, cross bar and web are assembled using pins, bolts or cylinders.

[0025] Furthermore, the rotational connection between two sections of the truss-type brackets is an axle pin connection.

[0026] Furthermore, the roller bracket also includes a third roller bracket extending laterally from the second roller bracket, and the structure of the third roller bracket is the same as that of the second roller bracket.

[0027] Of course, the fourth roller bracket, the fifth roller bracket, etc. can be expanded horizontally based on the third roller bracket. By increasing the number of horizontal roller brackets, more layers of arm sections can be assembled, and the assembly method is the same.

[0028] Compared with the prior art, the present invention provides a foldable boom section suit platform, which has the following beneficial effects:

[0029] (1) The mounting platform of the present invention can be mounted directly after the boom section is placed in it, without the need to adjust the position of the mounted boom section or change the hoisting position. It is efficient and convenient, and can effectively prevent the boom from being damaged by collision;

[0030] (2) The rollers in the sleeve platform of the present invention are arranged at a preset inclination angle, and the component force of gravity along the sleeve arm direction is used to offset most of the resistance in the sleeve arm process, so as to achieve the purpose of labor saving;

[0031] (3) The suit platform of the present invention is foldable and can be quickly unfolded when in use and quickly folded when not in use, thus occupying a small space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0064] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] Example 1

[0066] like Figure 3 , Figure 4 , Figure 5 , Figure 8As shown, the set platform of the present invention includes a main chord 11, a cross bar 12, a first roller bracket 31, and also includes a first platform 1 and a second platform 2 connected end to end for supporting the boom section. The first platform 1 and the second platform 2 both include two main chords 11 longitudinally arranged at the upper and lower ends and at least two cross bars 12 connected to the upper and lower main chords 11 at both ends and arranged transversely. The cross bar 12 on the first platform 1 is longer than the cross bar 12 on the second platform 2. At least two first cushion blocks 4 are arranged on the two main chords 11 of the first platform 1, and the first cushion blocks 4 are used to support the first cross-section boom section 101. At least two roller brackets are arranged on the two main chords 11 of the second platform 2, and the roller brackets include a first roller bracket 31 and a second roller bracket 32 ​​extending laterally from the first roller bracket 31. The first roller bracket 31 is used to support the second section arm section 102, including a first bracket body 311 arranged on the main chord 11, a first roller 312 installed on the first bracket body 311, and the second section arm section 102 is placed on the first roller 312; the second roller bracket 32 ​​is used to support the third section arm section 103, including a second bracket body 323 arranged on the cross bar 12, a second roller bracket body 321 movably connected to the second bracket body 323, and a second roller 322 installed on the second roller bracket body 321, and the third section arm section 103 is placed on the second roller 322.

[0067] The first section boom section 101 is a large section boom section, the second section boom section 102 is a medium section boom section, and the third section boom section 103 is a small section boom section, which are respectively equivalent to the main boom, tower boom, and auxiliary boom in the prior art.

[0068] In a specific implementation of the present embodiment, the first platform 1 and the second platform 2 are both truss-type supports. The truss-type support is a support having at least one web 13 arranged in a unit space surrounded by a main chord 11 and a cross bar 12. The web 13 is generally arranged obliquely, and its two ends are respectively arranged on the main chord 11 and the cross bar 12. However, when it is necessary to evenly distribute the roller supports, a section of the web 13 can be laterally extended inward from the main chord 11, so that the second support body 323 can be arranged on such a laterally extended section of the web 13.

[0069] In a specific implementation of this embodiment, the first platform 1 is configured as at least one truss-type support, and the second platform 2 is configured as at least one truss-type support, and the two truss-type supports are rotatably connected, such as Figure 7 As shown, the suit can be folded at least once, which greatly reduces the occupied area of ​​the suit and takes very little time to unfold and collapse.

[0070] In a specific implementation of this embodiment, at least two support frames 5 are further provided on the two main chords 11 of the second platform 2. The support frames 5 are used to place the main chords 11 of the first platform 1. The support frames 5 are blocks with a concave upper portion and a shape matching that of the main chords 11 of the first platform 1. Figure 6 shown.

[0071] In a specific implementation of the present embodiment, there is a second gasket 51 with a shape that fits the support frame 5; preferably, the second gasket 51 is fixed to the support frame 5 by bolts, and the second gasket 51 is made of flexible material to ensure flexible contact between the first platform 1 and the second platform 2; the support frame 5 is used to support the first platform 1. After the multiple arm sections are assembled, the assembled platform of the present invention is folded, the first platform 1 is rotated around the pin 6, and is placed in the support frame 5 on the second platform 2. The unfolding process is the opposite, which is quick and convenient. Fig.16 and Fig.17 shown.

[0072] In a specific implementation of this embodiment, the first cushion block 4 and the roller bracket are separate parts that can be assembled by pin connection or thread connection; this facilitates the maintenance of the first cushion block 4 and the roller bracket. When they are broken, they can be repaired by simply removing them, without the need to transport the entire set platform to a fixed point for repair. Figure 21 to Figure 23 shown.

[0073] In a specific implementation of this embodiment, a first gasket 41 is fixedly arranged on the first cushion block 4. Figure 4 shown.

[0074] In a specific implementation of this embodiment, at least two first cushion blocks 4 are symmetrically arranged on the two main chords 11 of the first platform 1 .

[0075] In a specific implementation of this embodiment, the first gasket 41 is fixed to the first cushion block 4 by screws. The first gasket 41 is made of flexible material to ensure flexible contact between the first platform 1 and the arm section to prevent damage to the arm section.

[0076] In a specific implementation of this embodiment, the main chord 11, the cross bar 12 and the web 13 are all welded or assembled from any one of seamless steel pipes, rectangular pipes, angle steels and plates. Fig.24 As shown; the main chord 11, the cross bar 12 and the web 13 are assembled at the intersection 14 by a pin or a bolt or a cylinder, respectively, as shown Fig.25 , Fig.26 , Fig. 27 shown.

[0077] In a specific implementation of this embodiment, the rotational connection between two sections of the truss-type brackets is a pin connection.

[0078] In a specific implementation of this embodiment, the roller bracket further includes a third roller bracket 33 extending laterally from the second roller bracket 32, and the structure of the third roller bracket 33 is the same as that of the second roller bracket 32. Fig.18 shown.

[0079] Of course, the fourth roller bracket, the fifth roller bracket, etc. can be expanded laterally based on the third roller bracket 33. By increasing the number of transverse roller brackets, more layers of arm sections can be assembled, and the assembly method is consistent.

[0080] Example 2

[0081] In order to achieve the purpose of labor saving of the present invention, the assembly can be completed without the assistance of a crane or other equipment. The difference between this embodiment and embodiment 1 is that:

[0082] like Fig.11 and Fig.12 As shown, at least two pairs of first pads 4 are symmetrically arranged on the two main chords 11 of the first platform 1, and at least two pairs of roller brackets are symmetrically arranged on the two main chords 11 of the second platform 2, and the height of each pair of first pads 4 and each pair of roller brackets increases successively from the head end of the first platform 1 to the tail end of the second platform 2, showing a gradient distribution.

[0083] The height of the roller bracket is arranged according to a preset inclination angle, that is, the first roller 312 and the second roller 322 are arranged according to a preset inclination angle, so that the component force of gravity along the arm sleeve direction can be used to offset most of the resistance in the arm sleeve process, so as to achieve the purpose of labor saving.

[0084] The movable connection between the second bracket body 323 and the second roller bracket body 321 can realize two assembly forms of the second roller bracket 32, namely, a working state and a non-working state. Fig. 9 and Fig.10 As shown, for example, the second bracket body 323 and the second roller bracket body 321 are connected together by the pin shaft 6, and the conversion between the two states is realized by rotating the pin shaft 6, as follows:

[0085] like Fig.13 and Fig.28 , Fig.29As shown, when the arm section needs two layers of sleeves, the second roller bracket 32 ​​is switched to a non-working state, that is, the pin shaft 6 is rotated, and the second roller 322 rotates downward along with the second roller bracket body 321 until the second roller 322 is in the lowest position, and then the first section arm section 101 is placed on the first platform 1, and the second section arm section 102 is placed on the second platform 2; at this time, because the second section arm section 102 has a preset inclination angle with the ground, multiple people can push the second section arm section 102 along the sleeve direction to guide it into the first section arm section 101, and pass through the arm section roller 7 of the first section arm section 101 until it is completely sleeved.

[0086] like Fig.14 and Fig.30 , Fig.31 As shown, when the arm section needs to be installed in three layers, the installation of the second section arm section 102 is completed first, and the second roller bracket 32 ​​is switched to the working state, that is, the pin shaft 6 is rotated, and the second roller 322 rotates upward with the second roller bracket body 321 until the second roller 322 is in the highest position, and then the third section arm section 103 is placed on the second platform 2; at this time, because the third section arm section 103 has a preset inclination angle with the ground, multiple people can push the third section arm section 103 along the arm installation direction to guide it into the second section arm section 102, and pass through the arm section roller 7 of the second section arm section 102 until it is completely installed, and the three sets of arm section installation are completed, as shown in FIG. Fig.15 As shown, during transportation, the assembled boom section can be hoisted as a whole and placed into the transport vehicle, and the disassembly process is the opposite.

[0087] In a specific implementation of the present embodiment, the connection portion between the first cushion block 4 and the first platform 1 and the connection portion between the first cushion block 4 and the second platform 2 are both provided with a connection method with adjustable height, such as a sleeve connection method, a threaded connection method or a cylinder connection method, preferably a sleeve connection method, and N holes are provided on the sleeve, and the height of the first cushion block 4, the first roller bracket 31, and the second roller bracket 32 ​​are adjusted by fixing with a pin shaft and a clip, so as to realize the inclination adjustment of the first cushion block 4 and the first roller bracket 31 and the second roller bracket 32 ​​to the suit platform of the present invention, such as Fig.19 and Fig. 20 shown.

[0088] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
